FIG. 1 to FIG. 21 are specific embodiments of the filter nozzle in the present application. - As shown in
FIG. 1 to FIG. 21 , thefilter nozzle 100 includes acasing 1, and apassage 11 is formed at thecasing 1 along a length direction of thecasing 1. Afirst opening 11a is formed at an end of thepassage 11, and thefirst opening 11a is configured for gas to be filtered to enter. Thepassage 11 includes a first filling section (not shown) and a second filling section (not shown). The first filling section is adjacent to thefirst opening 11a, and the first filling section is filled with two of a firstfunctional substance 2, asupport element 3 and a polylacticacid cotton element 4 along the length direction of thecasing 1. The second filling section is filled with one of a secondfunctional substance 5, thesupport element 3 and the polylacticacid cotton element 4. Thesupport element 3 is provided with agas passage 31 along the length direction of thecasing 1, and there are filter capsules or not in thesupport element 3. - If the first substance exists, there is no need to arrange the filter capsules at the
support element 3. If the first substance does not exist, the filter capsules can be arranged at thesupport element 3. If the first substance exists, the filter capsules can be arranged at thesupport element 3 to obtain two kinds of taste or increase the taste, and the like. - In the technical solution of the present application, when both the first filling section and the second filling section are filled with the polylactic
acid cotton element 4, since the material of the polylacticacid cotton element 4 is the polylactic acid cotton, the polylactic acid cotton is capable of adsorbing and capturing impurities from the gaseous substances (e-cigarette smoke) output from the atomizer, and the two polylacticacid cotton elements 4 act as a multi-filter to purify the smoke. When the polylacticacid cotton element 4 of the first filling section is connected to the polylacticacid cotton element 4 of the second filling section, they can form an integral part. When asupport element 3 exists, thesupport element 3 can support thecasing 1, and thesupport element 3 is provided with agas passage 31, which reduces the resistance of smoke transmission. In addition, by setting thesupport element 3, the length of the polylacticacid cotton element 4 in thepassage 11 can further be reduced, thereby reducing the suction resistance of thefilter nozzle 100. When thesupport element 3 of the first filling section is connected to thesupport element 3 of the second filling section, they can form an integral part. In an embodiment, the firstfunctional substance 2 and the secondfunctional substance 5 can be substances with medicinal effects or fragrances. By filling the firstfunctional substance 2 and/or the secondfunctional substance 5, the effect (such as fragrance and/or medicinal effect) of the gaseous substance output by the filter nozzle can be improved. When the first functional substance of the first filling section is connected to the second functional substance of the second filling section, they can form an integral part. In this embodiment, the first filling section is filled with two of the firstfunctional substance 2, thesupport element 3 and the polylacticacid cotton element 4 along the length direction of thecasing 1, and the second filling section is filled with one of the secondfunctional substance 5, thesupport element 3 and the polylacticacid cotton element 4. In this way, the performance of thefilter nozzle 100 can be optimized, and thefilter nozzle 100 can be combined with the atomizer, thereby meeting various requirements of users for filter nozzles and improving user experience. - The material of the polylactic acid cotton is the polylactic acid cotton. Since the density of the polylactic acid cotton ranges from 0.1g/cm3 to 1.0g/cm3 and the density of the polylactic acid cotton can affect the suction resistance of the smoke, the polylactic acid cotton within the density range of 0.1g/cm3-1.0g/cm3 can effectively improve the suction resistance of the
filter nozzle 100. For example, the density range of the polylactic acid cotton can be 0.1g /cm3, 0.2g /cm3, 0.3g /cm3, 0.4g /cm3, 0.5g /cm3, 0.6g /cm3, 0.7g /cm3, 0.8g /cm3, 0.9g /cm3, and 1.0g /cm3. The polylactic acid cotton is capable of adsorbing and capturing the tobacco tar from the smoke, providing filtration and cooling, thus, the oil absorption parameters of the polylactic acid cotton needs to be reasonably designed to enable the polylactic acid cotton to effectively and fully perform its intended functions. In an embodiment, the oil absorption range of the polylactic acid cotton is 5g/g-15g/g, and the polylactic acid cotton with this oil absorption range can more fully and effectively absorb and block the tobacco tar in the smoke to play a better filtering and cooling effect. In an embodiment, the polylactic acid cotton element has certain elasticity, and is filled in thecasing 1, so that the polylactic acid cotton element can be elastically abutted against the inner wall of thecasing 1. The polylactic acid cotton element with appropriate elasticity can ensure the stable arrangement of the polylactic acid cotton, and it is also convenient for filling the polylactic acid cotton. In an embodiment, the elastic recovery rate of the polylactic acid cotton is greater than 95%. - As shown in
FIG. 6, FIG. 9 ,FIG. 11, FIG. 12 ,FIG. 15 and FIG. 18 , asecond opening 11b is formed at another end of thepassage 11. Thesecond opening 11b is adjacent to the second filling section, and the second filling section is filled with the secondfunctional substance 5. When the secondfunctional substance 5 is powdery, aprotective cover 6 is provided at thesecond opening 11b to avoid leakage of the secondfunctional substance 5 and affect the energy efficiency of thefilter nozzle 100, and theprotective cover 6 can be removed when use, which is safe and hygienic. - It should be noted that in
FIG. 6 andFIG. 11 , since the secondfunctional substance 5 of the second filling section is powdery, to prevent the secondfunctional substance 5 from entering thegas passage 31 and blocking thegas passage 31, the side of thesupport element 3 close to thesecond opening 11b is provided with afilter membrane 7, and the secondfunctional substance 5 is supported by thefilter membrane 7 to ensure that the smoke can enter thegas passage 31 smoothly. - In an embodiment, as shown in
FIG. 1 ,FIG. 4 ,FIG. 16 andFIG. 21 , the side of the first filling section away from thefirst opening 11a is filled with the firstfunctional substance 2, and the firstfunctional substance 2 is powdery. When the second filling section is filled with thesupport element 3, since thesupport element 3 includes agas passage 31, the firstfunctional substance 2 may leak from thegas passage 31 of thesupport element 3 in the second filling section. Theprotective cover 6 at thesecond opening 11b can avoid the leakage of the secondfunctional substance 5 and the effect on the energy efficiency of thefilter nozzle 100. When thefilter nozzle 100 needs to be used, theprotective cover 6 may be removed, which is safe and hygienic. - It should be noted that, to make the filter nozzle safe and hygienic, a protective cover is provided at the second opening. Since the second opening is the end for people to suck, by setting the protective cover, the
filter nozzle 100 is safe and hygienic, and the user experience is improved. - In an embodiment, as shown in
FIG. 20 and FIG. 21 , the first filling section is filled with the firstfunctional substance 2 and thesupport element 3, and thesupport element 3 is adjacent to thefirst opening 11a. The firstfunctional substance 2 is granular or powdery. By covering thefilter membrane 7 at thefirst opening 11a, since thefilter membrane 7 is a gas-permeable film with certain gas permeability, thefilter membrane 7 can block thefirst opening 11a, and allow smoke to pass through effectively. Thefilter membrane 7 has a certain degree of adsorption capability, and can partially block tobacco tar, condensate, and the like. Thefilter membrane 7 can also effectively prevent the firstfunctional substance 2 from being scattered through thegas passage 31 of thesupport element 3. It can be understood that thefilter membrane 7 can also be provided between thesupport element 3 and the firstfunctional substance 2. - In an embodiment, the filter membrane is arranged along with the first
functional substance 2 and the secondfunctional substance 5. For example, as shown inFIG. 2 ,FIG. 4 ,FIG. 5 ,FIG. 10 to FIG. 13 andFIG. 20 , when the first functional substance is arranged in the first opening, the filter membrane is covered at the first opening. As shown inFIG. 6 ,FIG. 15 andFIG. 20 , when the second functional substance is provided at the second filling section and a support element is provided at the side of the first filling section away from the first opening, a filter membrane is provided at the side of the support element away from the first opening. - In an embodiment, as shown in
FIG. 10 to FIG. 13 , when the side of the first filling section close to thefirst opening 11a is filled with the firstfunctional substance 2, the firstfunctional substance 2 is granular or powdery, and afilter membrane 7 is provided at thefirst opening 11a. Since thefilter membrane 7 is a breathable film with a certain degree of gas permeability, thefilter membrane 7 can block thefirst opening 11a, and can effectively allow the smoke to pass through. Thefilter membrane 7 has a certain degree of adsorption capability, and can partially block tobacco tar, condensate, and the like. Thefilter membrane 7 can also effectively prevent the firstfunctional substance 2 from being scattered from the first filling section. - The
filter membrane 7 can be made of a plurality of materials. For example, thefilter membrane 7 can be made of plastics, silica gel and the like. Specifically, in the present application, thefilter membrane 7 can be made of papery or lactic acid cotton. In this way, since both paper and lactic acid cotton are breathable materials, the smoke can effectively pass through. Moreover, paper and lactic acid cotton have a certain degree of adsorption capability, and can partially block tobacco tar, condensate, and the like. In addition, both paper and lactic acid cotton have the small weight, thereby effectively reducing the overall weight of thefilter nozzle 100. - To ensure that the
filter membrane 7 can allow gas to pass through while the firstfunctional substance 2 and the secondfunctional substance 5 are blocked, the porosity of thefilter membrane 7 ranges from 80 mesh to 120 mesh. In another embodiment, the porosity of thefilter membrane 7 can be set according to the requirements, which will not be limited in this embodiment. - To enhance the energy efficiency of the
filter nozzle 100, as shown inFIG. 2 andFIG. 3 , thesupport element 3 filled in the first filling section is provided withfilter capsules 8, and thefilter capsules 8 are abutted against at least part of the inner wall surface of thegas passage 31. Thefilter capsules 8 are provided at thesupport element 3, and thefilter capsules 8 flow out a liquid with a fragrance when thefilter capsules 8 are crushed, so that the smoke flowing through thesupport element 3 will have a corresponding taste, and the tastes of electronic cigarettes are diversity. In addition, thefilter capsule 8 is abutted against at least part of the inner wall surface of thegas passage 31, so that thefilter capsule 8 is not easy to move, and the user can locate and crush thefilter capsule 8 easily. The filter nozzle of the present application has good user experience and strong market competitiveness. - It should be noted that there are various materials of the
support element 3. For example, the material of thesupport element 3 can be paper. In an embodiment, the material of thesupport element 3 is the safe and non-toxic silicone gel. The silicone gel has certain elasticity, which not only makes it convenient for processing thegas passage 31, but also makes the operation simple when thefilter capsule 8 needs to be installed at thesupport element 3, and thesupport element 3 is not easily deformed after the user squeezes thefilter capsule 8. Thefilter capsule 8 is located in the middle of the inner core, which can avoid that thefilter capsule 8 is too close to the second opening to cause the splashed liquid to fly directly into the user's mouth when thefilter capsule 8 is broken affecting the taste and causing safety hazard. The number offilter capsules 8 at thesupport element 3 is not limited, which can be one or more. When a plurality of thefilter capsules 8 are provided, thefilter capsules 8 with different tastes can be chosen to form a richer taste, or a combination of thefilter capsules 8 with a single taste can be chosen to enhance the concentration of the taste and extend the duration of taste. - In an embodiment, the
filter capsule 8 includes a casing (not shown) and the liquid inside the casing. When thefilter capsule 8 is crushed by external force, the liquid will flow out. The smoke outputted from the electronic cigarette will has different tastes, fragrance, functions, and the like due to the different formula of the liquid. The liquid may be scented liquids with different fragrances or tastes, such as creamy liquids, mint liquids, and the like, or medicinal liquids with health efficacy. In an embodiment, thefilter capsule 8 is shaped in a sphere with a diameter of about 2.5-4 mm. - In order to reduce the suction resistance of the
filter nozzle 100, as shown inFIG. 3 , when the second filling section is filled with the polylacticacid cotton element 4, thepassage 11 further includes a third filling section, and the third filling section is provided at the side of the second filling section close to thesecond opening 11b, and the third filling section is filled with thesupport element 3. In this way, since thesupport element 3 is provided with agas passage 31 and the third filling section is filled with thesupport element 3, the transmission resistance of the gaseous substance can be reduced, the length of the polylacticacid cotton element 4 in thecasing 1 can be reduced, and the suction resistance of thefilter nozzle 100 can be reduced, thereby improving the user experience. - As shown in
FIG. 4 , in an embodiment, the first filling section is filled with the firstfunctional substance 2 and thesupport element 3. When the firstfunctional substance 2 is granular or powdery and is adjacent to thefirst opening 11a, the second filling section is filled with thesupport element 3, so that the firstfunctional substance 2 can first contact with the smoke, and the firstfunctional substance 2 can be better heated and release fragrance or medicinal effect, thereby improving the efficacy of the smoke. By setting twosupport elements 3 in thecasing 1, thegas passages 31 of the twosupport elements 3 are communicated with each other, and the smoke directly enters the mouth of the smoker through thegas passage 31 of thesupport element 3, which reduces the transmission resistance of gaseous substance and the suction resistance of thefilter nozzle 100, thereby improving the user's smoking experience. In this case, the twosupport elements 3 may be integrated into one. - As shown in
FIG. 5 , in an embodiment, when the first filling section is filled with the firstfunctional substance 2 and the polylacticacid cotton element 4, the firstfunctional substance 2 is granular or powdery and is adjacent to thefirst opening 11a, and the second filling section is filled with the polylacticacid cotton element 4, so that the firstfunctional substance 2 can first contact with the smoke, and the first functional substance can be better heated and release fragrance or medicinal effect, thereby improving the efficacy of the smoke. Two polylacticacid cotton elements 4 are provided in thecasing 1, and the two polylacticacid cotton elements 4 are made of the polylactic acid cotton. The polylactic acid cotton can absorb and block the impurities in the tobacco tar of the smoke to play a multi-filtration and purification role. In this way, the smoke with a fine taste is finally discharged and is more pure, which improves the user experience. When the user smokes, the mouth will contact with the polylacticacid cotton element 4. Compared with silicone, the polylactic acid cotton is softer and more elastic, and has a better touch. In this case, the two polylacticacid cotton elements 4 can be integrated in to one. - In an embodiment, as shown in
FIG. 14 , when the first filling section is filled with the polylacticacid cotton element 4 and thesupport element 3, and the polylacticacid cotton element 4 is adjacent to thefirst opening 11a, the second filling section is filled with the polylacticacid cotton element 4. In this way, two polylacticacid cotton elements 4 are provided in thecasing 1, and the two polylacticacid cotton elements 4 are made of the polylactic acid cotton. The polylactic acid cotton can absorb and block impurities in the tobacco tar of the smoke to play a multi-filtration and purification role. Thesupport element 3 can support the outer tube, and thesupport element 3 includes agas passage 31 extending along the length direction of thecasing 1. In this case, the smoke filtered by the polylactic acid cotton in the first filling section can enter thegas passage 31, then the smoke can gather in thegas passage 31 and will be filtered by the polylactic acid cotton in the second filling section, and the smoke with a fine taste is finally discharged and is more pure, which improves the user experience. When the user smokes, the mouth will contact with the polylacticacid cotton element 4. Compared with silicone, the polylactic acid cotton is softer and more elastic, and has a better touch. In this case, if thefilter capsule 8 exists in thesupport element 3, the suction effect will be better. - It should be noted that the
gas passage 31 may be shaped in a straight line or in a curve, and the number of thegas passage 31 may be one or multiple, which is not limited in this embodiment. - In an embodiment, as shown in
FIG. 10 , when the first filling section is filled with the firstfunctional substance 2 and thesupport element 3, the firstfunctional substance 2 is granular or powdery and is adjacent to thefirst opening 11a, and the second filling section is filled with the polylacticacid cotton element 4. In this case, the firstfunctional substance 2 can first contact with the smoke, and the firstfunctional substance 2 can be better heated and release fragrance or medicinal effect, thereby improving the efficacy of the smoke. Then the smoke passes through thegas passage 31 of thesupport element 3, which can reduce the transmission resistance of the gaseous substance, and the smoke will be filtered by the polylacticacid cotton element 4 in the second filling section. The suction resistance of thefilter nozzle 100 will be reduced due to the reduction of the length of the polylacticacid cotton element 4, thereby improving the user smoking experience. - In an embodiment, the first
functional substance 2 is granular or powdery, so that the firstfunctional substance 2 is conveniently stored in thefirst casing 1. - It should be noted that, in an embodiment of the present application, the particle size of the first
functional substance 2 ranges from 0.0001 µm to 1000 µm. In this way, within this particle size range, the firstfunctional substance 2 can form the solid aerosol along with the airflow when the electronic cigarette is smoked by the user, and the firstfunctional substance 2 at the micro-nano level is also easier to be absorbed by the human body. In other embodiments, the particle size of the firstfunctional substance 2 can be determined according to the requirements, which is not limited in this embodiment. In addition, in another embodiment similar toFIG. 10 , the polylacticacid cotton element 4 is for filtering out substances harmful to the human body from the smoke, and the functional substances in the firstfunctional substance 2 will not be filtered out or can partially pass through, thereby ensuring that the components in the firstfunctional substance 2 can pass through effectively. - In an embodiment, the second
functional substance 5 is powdery, so that the firstfunctional substance 2 and the smoke can form an aerosol to enter the oral cavity or nasal cavity of the smoker along with the smoke. - It should be noted that the first
functional substance 2 can be made of many kinds of materials, and the firstfunctional substance 2 is a substance with a medicinal effect or fragrance. For example, in the present application, the firstfunctional substance 2 includes at least one of caffeine, essential oil, nicotine, probiotics, hyaluronic acid or vitamin D. - It should also be noted that the second

For example, in the present application, the secondfunctional substance 5 includes at least one of freeze-dried powder, caffeine powder, nicotine-containing powder, probiotic powder, hyaluronic acid powder and vitamin D-containing powder. - In addition, it should be noted that both the first functional substance and the second functional substance are composed of a physiologically active substance and a casing wrapping the physiologically active substance. The physiologically active substance can be the mixture of one or more of immobilized probiotics, fermented products of probiotics, other natural active substances with health care and therapeutic effects and their extracts. Health care and therapeutic effects may include clearing the throat, refreshing the mind, improving memory, enhancing immunity, regulating intestinal flora, losing weight, improving skin, improving and assisting in lowering blood lipids and blood sugar, and anti-aging. In actual scenarios, different physiologically active substances are reasonably combined to achieve effects such as maintaining health in the oral cavity and the respiratory tract, refreshing the mind, accelerating sobering up, losing weight, beautifying and anti-aging. In this embodiment, the physiologically active substance is the probiotic or the fermented product of probiotics. The materials of the
casing 1 include one or more of cyclodextrin, gelatin, sodium alginate, and gum arabic. After the physiologically active substance is wrapped by thecasing 1, on the one hand, the direct contact between the physiologically active substance and air can be avoided, thereby ensuring the unaffected activity; on the other hand, the selection range of physiologically active substances can be further extended to active substances that are difficult to atomize, easy to oxidative denaturation, and poor thermal stability. - In this embodiment, the first
functional substance 2 is the freeze-dried powder, which is convenient for storage and absorption by the human body. In an embodiment, the firstfunctional substance 2 can be processed into the powder, specifically, it can be obtained by various methods such as low-temperature pulverization, spray drying, and freeze-drying. - In an embodiment, the
casing 1 includes a molded paper layer, a printed layer and a protective layer stacked sequentially from an inside of the casing to an outside of the casing. In this way, thecasing 1 is composed of stacked layers, including the molded paper layer, the printed layer and the protective layer, which not only securely holds the fillers within the first and second filling sections, but also enhances the aesthetics and recognition of thefilter nozzle 100 through printed identifications, patterns, and the like. The protective layer will protect the printed layer. On one hand, the protective layer will avoid the direct contact between the printed ink and the user's mouth, reducing potential safety risks.

Besides, thefilter nozzle 100 is easier for users to hold and suck due to the longer length of thecasing 1. In an embodiment, the length of thecasing 1 ranges from 33 mm to 35 mm. For example, the length of thecasing 1 may be 33 mm, 33.6 mm, 34 mm, 34.5 mm, 35 mm and the like. Through multiple tests, the inventor found that when the length of thecasing 1 ranges from 32 mm to 44 mm, when the outer diameter of thecasing 1 ranges from4mm 7 mm and when the thickness of thecasing 1 ranges from 0.38 mm to 0.45 mm, impurities can be fully filtered out. Under this condition, the length of thecasing 1 is reduced. Since the length of the polylacticacid cotton element 4 will be reduced accordingly, on the one hand, the gas permeability of the polylacticacid cotton element 4 will be better and the smoke flavor more full; on the other hand, consumables will be saved and costs will be reduced. In addition, when thefilter nozzle 100 with this length is matched with smoke generating components in the current conventional electronic cigarette, the length ratio is more suitable and the appearance is better. In an embodiment, the outer diameter of thecasing 1 is 7 mm, and the thickness of thecasing 1 is 0.4 mm. In this way, thecasing 1 of this size can not only fix the polylacticacid cotton element 4 well, but also play a blocking role, to reduce potential safety hazards, consumables of thecasing 1 and costs. - When the first filling section is filled with the polylactic acid cotton and the polylactic acid cotton is adjacent to the
first opening 11a, a distance between an end of the polylactic acid cotton close to thefirst opening 11a and a peristoma of thefirst opening 11a is A1, and A1 is not less than 1 mm and not greater than 6 mm.
